Cloud Computing and Grid Computing are emerging technologies but what are the difference
Cloud Computing
At a basic level, cloud computing is simply a means of delivering IT resources as services.
Almost all IT resources can be delivered as a cloud service: applications, compute power,
storage capacity, networking, programming tools, even communications services and
collaboration tools.
Cloud computing began as large-scale Internet service providers such as Google,
Amazon, and others built out their infrastructure. An architecture emerged: massively
scaled, horizontally distributed system resources, abstracted as virtual IT services and
managed as continuously configured, pooled resources. This architectural model was
immortalized by George Gilder in his October 2006 Wired magazine article titled “The
Information Factories.” The server farms Gilder wrote about were architecturally similar
to grid computing, but where grids are used for loosely coupled, technical computing
applications, this new cloud model was being applied to Internet services.
“In this architecture, the data is mostly resident on servers ‘somewhere on the Internet’ and the application runs on both the ‘cloud servers’ and the user’s browser.” —Eric Schmidt in ‘Information Factories’ by G. Gilder
Grid Computing
Grid computing (or the use of a computational grid) is the application of several computers to a single problem at the same time – usually to a scientific or technical problem that requires a great number of computer processing cycles or access to large amounts of data.
Grid computing depends on software to divide and apportion pieces of a program among several computers, sometimes up to many thousands. Grid computing can also be thought of as distributed[citation needed] and large-scale cluster computing, as well as a form of network-distributed parallel processing[citation needed]. It can be small -- confined to a network of computer workstations within a corporation, for example -- or it can be a large, public collaboration across many companies or networks.
